Description

Our plano-convex, aspherical TPX lens series is optimized for collimation and focusing in THz optics. The TPX35 is a lens with an effective focal length (EFL) of 35 mm and a diameter of 1”, designed for optimal collimation of highly divergent THz radiation. The TPX50 is a 1.5” lens with 50 mm EFL, featuring the same numerical aperture as the TPX35. Both TPX35 and TPX50 are optimized for collimation in combination with our TERA15-FC antenna series. TPX100 and TPX200 are 1.5” lenses with 100 mm and 200 mm EFL, respectively, optimized for focusing the THz radiation for increased working distance in the terahertz path. The TPX35 is mounted in a 1” lens holder with a clear aperture of 23.0 mm, the TPX50/100/200 lenses are mounted in a 1.5” lens holder with a clear aperture of 35.5 mm.
